[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A plastic pump head assembly device includes an assembly seat 1, a base 11 provided at one end of the assembly seat 1, and a guide groove 12 provided at the end of the assembly seat 1 away from the base 11. A support plate 2 is slidably installed in the guide groove 12, an assembly motor 3 is provided on the base 11, a pump head 4 is provided on the support plate 2, a plurality of evenly distributed through holes 21 are provided on the support plate 2, a support mechanism 22 is provided in the through holes 21, a bracket 5 is fixedly installed at the end of the support plate 2 away from the assembly motor 3, a guide opening 51 is provided on the bracket 5, and a pressing mechanism 52 corresponding to the supporting mechanism 22 is provided in the guide opening 51. When the pump head 4 is placed on the support plate 2, the pump head 4 can be fixed by the supporting mechanism 22 and the pressing mechanism 52, and the assembly motor 3 can be directly placed on the base 11. By pushing the support plate 2, the pump head 4 can be brought into contact with the assembly motor 3, and assembly can be performed directly.

[0023] Reference Figure 3 The support mechanism 22 includes a guide sleeve 221 fixedly mounted in the through hole 21, a support rod 222 slidably mounted in the guide sleeve 221, and a spring 223 disposed between the support rod 222 and the guide sleeve 221. The ends of the spring 223 are respectively fixedly connected to the support rod 222 and the guide sleeve 221. When the pump head 4 is placed on the support plate 2, the support rod 222 at the corresponding position can be pressed, allowing the support rod 222 at this position to slide in the guide sleeve 221. The support rods 222 around the pump head 4 can limit the pump head 4.

[0024] Reference Figure 3 The end of the support rod 222 away from the guide sleeve 221 is fixedly mounted with a rubber head 224, and a plurality of convex bumps are provided on the rubber head 224. When the rubber head 224 on the support rod 222 contacts the pump head 4, the pump head 4 can be prevented from being scratched, thereby playing a protective role.

[0025] Reference Figure 4The pressing mechanism 52 includes a slider 521 slidably mounted within the guide opening 51, an adjusting screw 522 axially extending through the slider 521, and a pressing plate 523 rotatably mounted on one end of the adjusting screw 522. The adjusting screw 522 is threadedly connected to the slider 521. By rotating the adjusting screw 522, the pressing plate 523 can come into contact with the top of the pump head 4, thereby pressing the pump head 4 and ensuring that the pump head 4 is fixed.

[0026] Reference Figure 2 The pressing plate 523 is made of hard rubber material, and a rotating plate is fixedly installed on the end of the adjusting screw 522 away from the pressing plate 523. The adjusting screw 522 can be manipulated by the rotating plate, and the pressing plate 523 is made of hard rubber material so that it can change its shape in a small range, so as to fix pump heads 4 of different sizes.

[0027] Reference Figure 1 The cross-section of the guide groove 12 is in the shape of a convex character, which ensures that the support plate 2 is more stable when sliding.

[0028] The specific working principle of this utility model is as follows:

[0029] When the pump head 4 is placed, the supporting plate 2 can be used to push the supporting plate 2 so that one end of the supporting plate 2 can be in contact with the assembly motor 3. The pump head 4 can then be assembled with the supporting plate 222 and the assembly motor 3. After the pump head 4 is placed, the adjusting screw 522 can be rotated by the rotating plate, and the pressure plate 523 can be manually limited. When the adjusting screw 522 is rotated, the pressure plate 523 can be driven to move and fit the pump head 4. The pump head 4 can be pressed tightly to fix the pump head 4 on the supporting plate 2. The coordinated use of the supporting plate 222 and the pressure plate 523 can fix pump heads 4 of different sizes, which is more convenient to use. After the pump head 4 is fixed, the supporting plate 2 can be pushed so that one end of it contacts the assembly motor 3, and the pump head 4 and the assembly motor 3 can be assembled by bolts. After the assembly is completed, the entire plastic pump can be removed from the assembly seat 1.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
